Mesmerising (and sea-sickness-inducing) footage of an enormous waterspout hovering over the Black Sea, off the coast of Russia.
"The weather in the sky tightened in a matter of minutes," said the filmer. "First a rain shower, then tornadoes began to appear around the ship." That was all he had time to capture.
The footage was filmed on a boat near Betta, southern Russia, on July 16.
